By 1770 a fortified encampment called Fort Savannah was established at the Lewis Spring. In 1774, Lt Governor Dunmore of Virginia instructed then-Colonel Andrew Lewis to gather “willing and able men” to go to the great Kanawha River and stand against the Native American forces that were attacking the Greenbrier Valley. In what became known as Lord Dunmore’s War, over 1,490 men were assembled, some at Fort Pitt at present-day Pittsburgh, and others at Fort Union, on the site of present-day Lewisburg. These recruits included Lewis’s brother Charles, and others which history books refer to as one of the most remarkable assemblages of frontier leaders in American history. Thirteen were men of political and military distinction. Lewis’s army marched down the New and Kanawha Rivers to the Ohio River, where they intended to cross over and invade the Ohio Country, which was the home of the Shawnees. The Native Americans, led by Cornstalk, attempted to cut them off at the mouth of the Kanawha, where they fought an inconclusive battle that came to be known as the Battle of Point Pleasant
